Aside from his blue fur matching IBM’s blue corporate colors, it’d be easy to assume there was little connection between Sesame Street’s treat-loving puppet Cookie Monster and the giant computer firm. Back in the 1960s, however, Jim Henson was put in charge of creating a training video for Big Blue. To that end he lent his voice and his puppets to the task, bringing out a prototypical Cookie Monster muppet.

A year prior to IBM tasking him with creating a training film, Henson was hired by General Foods to create a commercial focused on food-craving monsters. He made three unique puppets for three types of food but the commercials were scrapped before airing; the hungry monsters were put on the shelf–they wouldn’t have to wait long to see more action in front of the camera.

When it came time to produce the video for IBM, Henson pulled the early version of Cookie Monster out to serve as a confused and destructive end-user.In the training film called Coffee Break Machine, focused on the importance of design and user interfaces, Cookie Monster grows frustrated with the complexities of the coffee machine and ends up devouring it with explosive results.

After that, Cookie Monster appeared in a handful of commercials before settling in as a permanent member of the Sesame Street cast.
